The inspection app can also be easily set up! It reads the addresses on envelopes and postcards (OCR, barcode) with the camera, and keeps a log of sequential inspections and images!

Under the Personal Information Protection Law, inspecting shipments addressed to individuals has become essential. For contractors handling the insertion, processing, and shipping of mail, shipments addressed to individuals often contain personal and privacy information. To prepare for potential shipping accidents such as misdeliveries or incorrect addressee entries, it is likely that manual inspections are being conducted. While it would be ideal to conduct a full inspection for safety, some companies may resort to sampling due to the enormous volume of shipments. This cannot be considered a foolproof inspection system, leaving concerns about shipping accidents. Our "Camera Inspection Device" reads information such as OCR characters, postal codes, and barcodes on the address portion of envelopes and postcards, allowing for easy sequential inspections and data verification. By logging data and images simultaneously during reading, we can retain data for secondary use and maintain inspection history. Why not take this opportunity to review the pre-shipment inspection of your mail? In addition to address inspections, we also offer appearance inspections, matching checks during picking, and custom solutions, so please feel free to consult with us.
